Claims.

My invention relates to work-holding devices for holding small metalparts, such as jewelers and Opticians have to do with, to permit thoseparts to be held in proper relative position while they are beingsoldered or brazed together.

One object of my invention is to provide such a device in which smallmetal parts may be held and adjusted in all planes relative to eachother, to permit broken parts of various shapes to be properlypositioned before being soldered or brazed together.

The things that a jeweler or optician may be called upon to fix may havevarious shapes, sizes and relative angular dispositions. For example,the various parts of the frames, nose-pieces, or temples of a pair ofspectacles, when broken, present pieces of odd shapes, sizes, andangular relationships. To hold them in proper relative position forrejoining, the holding devices must be capable of relatively universalmovement.

In order to provide for holding two broken or separated partsin properrelationship for fixing or rejoining by soldering or brazing, theholding devices or vises are arranged so that each vise is movable abouttwo axes, and also so that the vises may be adjustably and variablyspaced from each other. Thus, articles of different shapes and ofvarious other sizes may be accommodated.

Another object of my invention is to provide a drawer for holding smallarticles like screws, sheets and bits of gold leaf, and other smallparts, which is provided with compartments shaped to permit such smallparts to be easily removed by hand.

An apparatus constructed in accordance with my invention is illustratedin the accompanying drawings in which:

Figure 1 is a plan view of the work-holding device;

Figure 2 is an elevational front view of the device of Figure 1;

Figure 3 is a schematic view showing two parts of a broken member heldtogether to be soldered or brazed by energy derived from an electriccircuit;

Figure 4 is an elevational end view of the Workholder;

Figure 5 is an enlarged side view, partially in section, of one of themovable vise clamps; and

Figures 6 and '7 are, respectively, plan and vertical side sectionalviews of a modified form of drawer for small articles.

As shown in the drawings, the work-holding device embodying my inventioncomprises a main base I, an auxiliary base 2, hinged thereto by hinges3, a vertical plate or standard 4 rotatably secured to the auxiliarybase 2' and supporting a vise 5 having two jaws 6 and I, and a secondvertical plate 8 rotatably secured to the auxiliary base 2 andsupporting a second vise 9 having two jaws I0 and II.

The vertical plate 4 is provided with a lug l2 that serves as a bearingabout a pin on the auxiliary base 2. A friction spring 14 holds thevertical plate against casual displacement from a selected adjustedposition. A cap screw I5 holds the spring 14 in position to exertfrictional pressure against the lug l2 of the vertical plate 4, toprevent casual displacement.

The vise 5 is adjustably, rotatably supported on plate 4 by a threadedscrew I! and lock nut H3. The vise jaws l0 and II can thus be opened bya biasing separating spring l9 to hold a desired object and then lockedin position on the plate 4 in the position required. At the same timethe plate 4 may be rotated about the axis of the lug l2, as may bedesired.

The second Vertical plate 8 is provided with a lug 2i that serves as abearing about a pin on the auxiliary base 2. A friction spring 22 holdsthe plate 8 against casual displacement from a selected adjustedposition. A cap screw 23 holds the spring 22 in position to exertpressure against the lug 2| of the plate 8, to prevent casualdisplacement after the plate 8 is moved to a selected adjusted position.

The plate 8 is relatively long and is provided with a horizontal slot25, in which the vise 9 is movable to a selected position. As shown inFigure 5, the vise 9 comprises the two vise jaws l0 and H, normallybiased to open position by a helical spring 21 encircling an adjustmentscrew 28. The adjustment screw 28 is secured to the jaw Ill and extendsthrough jaw H and through a threaded cylindrical extension 29 of jaw H.A washer 30 presses against the outer end of ex tension 29, and anadjusting nut 3! on the threaded screw 28 adjusts the opening betweenjaws l0 and H of the vise. A guide pin 32 prevents rotary movementbetween jaws l0 and II.

A second adjusting and positioning nut 33 and washer 34 secure the vise9 on the plate 8. A handle 35 is provided for the nut 33.

As shown in Figure l, the plates 4 and 8, supporting the two Vises 5 and9, are movable about the respective axes of the lugs l2 and 21 on plates4 and 8. Inaddition, vise 9 is horizontally movable on plate 8 to varythe opening between the two Vises. When the parts to be held by thevises are in proper position, as in Figure 3, a small piece of gold orbrazing alloy is placed on the parts where they are to be joined. Oneconductor 4!! of an electric circuit 4| is connected to terminal post42, and the other conductor 43 is connected to an electrode such as acarbon pencil 44 which is placed against the brazing metal until it ismelted and flows into position to braze the two broken parts.

The auxiliary base 2 is pivoted on the main base by the hinges 3 topermit the vises to be rotated about the horizontal axis of the hinges,if necessary to place the broken parts in corresponding position.

In the structure in Figure 1, I have provided several pockets or wells45 in which to keep small parts, like screws or parts of gold leaf, orthe like. A cover 46 is hinged at hinges 41 to cover the wells 45. Alatch 48 is provided to hold the cover closed. Instead of wells in thebase as shown, a drawer may be provided if desired. In order to enablethe small parts to be readily taken out of the wells, they may be formedas in Figures 6 and 7 to provide an overhanging front edge 49, underwhich or against which the nail or skin at the end of a thumb may beheld while the forefinger moves the desired part out of the well.

My invention is not limited to the specific details as shown, since theymay be variously modified, without departing from the spirit and scopeof the invention as set forth in the appended claims. 1
